Micro-Adjust Your Router Table Fence

The router table in my shop gets lots of use. But it’s always
difficut to make fine adjustments to the fence. So I built the
micro-adjuster you see in the photo above using spare parts I had around
the shop.

The adjuster is easy to build. Start by drilling and tapping a strip of
¼″ aluminum to accept a piece of threaded rod. And then bend
the aluminum strip into an “L” shape.

Next, drill two holes in a hardwood adjusting block. One horizontal hole
for the threaded rod and a vertical one for the hold-down. Then you can cut
a dado at the bottom of the fence to hold the piece of L-shaped aluminum in
place.

Assembly. Put the pieces together by slipping the threaded
rod through the adjusting block and adding washers and locknuts, like you
see in the drawing and detail below. This allows the aluminum strip
attached to the fence to be moved forward and backward one thread at a time
when you make fine fence adjustments.

Fence Adjustment. To use the micro-adjuster, you’ll
first need to lock down the opposite end of the fence. Then lock down the
micro-adjuster by tightening the knob on top of the adjusting block. Use
the turning knob to adjust the fence to the desired position. Once the
fence is located where you want it, lock down the other end of the fence.
Then all that’s left is to turn on your router and you’re ready
to go.
